A model for evaporative casting of polymeric membranes incorporating convection due to density changes

Solvent effect on morphology and CO2/CH4 separation performance of asymmetric polycarbonate membranes

“…Similar behavior was exhibited by the membranes prepared using the chloroform-alcohol solvents mixtures (Figs. [10][11][12]. The experimental data show a higher permeance for both CO 2 (Fig.…”

“…[10][11][12]]. A strong influence of the mass transfer process was expectedly predicted on the formation of the film structure as well as the substructure.…”

Phase diagram of ternary polymeric solutions containing nonsolvent/solvent/polymer: Theoretical calculation and experimental validation

“…In many literature in this field of research, the FloryeHuggins theory has been used to describe the thermodynamic and equilibrium calculations in ternary polymer, solvent and nonsolvent systems [15,16,19,20,25]. However, the FloryeHuggins theory suffers from the necessity on experimental determination of binary interaction parameter g ij [26e28], and using an inappropriate value of these parameters, through correlation of available binodal data, results in severe predictions by FloryeHuggins theory [8].…”

“…(18) for equilibrium calculations in CRS theory [42,43], while one may obtain Eq. (19) for CRS theory by simplifying Eq. (17).…”

Application of non-equilibrium thermodynamics and computer aided analysis to the estimation of diffusion coefficients in polymer solutions: The solvent evaporation method☆

“…The industrial importance of the acetone evaporation as a major step in the dry cast and as a precursor step in the wetcast phase-inversion process has led to extensive modeling studies [59,61,[109][110][111][112][113][114][115][116][117][118]. In all studies it is evident that the solvent evaporation process is controlled by the diffusion of the solvent in the polymer solution.…”
